Implement Jukebox Mode

[Bhaalisto]

I would like to suggest a feature for the future:
A kind of musicbox, where music and videos can be played without having to be sung.
As a break filler, so to speak.
The feature is already included in UltraStar Deluxe. I hope now everyone knows what I mean. ;-)

I like this idea, but that would be a bigger change. So I don't think, that I can do this alone or in the next time. But I really like this idea (I know it from USDx) and maybe someday, if I don't know what to do with my spare time... ;)
